I've implemented a ValueChangeListener, to handle the change of the radio
button, but I'm not sure how to change the value in my Seam component, to
reflect the value change. I'm sure I am supposed to be looking up the Seam
component a different way, since it fails with a ClassCastException when I try
to get the Seam component from FacesContext.
The question now is, in what way is this code different when we're dealing with
Seam components (SFSBs) vs. standard JSF managed beans? It finds the component
just fine, and even tells me the beanClass is
com.project.actions.EditUserRecordAction.
Here is the code:
package com.project.util;
|
| import javax.faces.application.Application;
| import javax.faces.context.FacesContext;
| import javax.faces.event.AbortProcessingException;
| import javax.faces.event.ValueChangeEvent;
| import javax.faces.event.ValueChangeListener;
|
| import com.project.actions.EditUserRecordAction;
|
| public class StateSelectorChangeListener implements ValueChangeListener {
|
| public void processValueChange(ValueChangeEvent event) throws
AbortProcessingException {
| FacesContext facesContext = FacesContext.getCurrentInstance();
| Application app = facesContext.getApplication();
| Object myObj =
app.getVariableResolver().resolveVariable(facesContext, "editProfileAction");
| try {
| EditUserRecordAction editRecordBean =
(EditUserRecordAction)myObj;
| editRecordBean.setSelectedState((String)event.getNewValue());
| } catch (RuntimeException e) {
| e.printStackTrace();
| }
| }
|
| }
|
@Stateful
| @Name("editProfileAction")
| @Scope(SESSION)
| public class EditUserRecordAction implements EditUserRecord, Serializable {
| ...
| public void setSelectedState(String selectedState){
| this.selectedState = selectedState;
| }
| }
